Now make it life size
Here’s a scale model of the classic Playstation game Wipeout.
It uses quantum levitation, superconductors, liquid nitrogen, and incredibly detailed models of the cars in Wipeout. They’re able control the speed and direction of the cars electronically. Somebody get on making one of these I can drive. Never mind, it’s totally fake, but here’s a choo-choo that does the same thing. Thanks for the link, [Ben].
Found a use for eight copies of Deep Impact
Where do you keep all your wire? [Paul] keeps his inside VHS tapes. It’s one of the most efficient ways of storing wire we’ve seen, just don’t touch those VHS copies of the original Star Wars trilogy.
There’s MAME machines for pinball?
MAME arcade machines are old hat, but we’ve never seen something to emulate pinball. The build uses two LCD monitors, a small computer and PinMAME. There’s videos in the build log; tell us if we’re stupid for wanting to build one. Thanks go to [Adrian] for sending this one in.
LEGO binary to decimal conversion
[Carl] is doing a few experiments to see if it’s possible to build a calculating machine out of LEGO. He managed to convert four bits of binary into decimal. We’ve seen a LEGO Antikythera mechanism but nothing on the order of an Analytical Engine or some Diamond Age rod logic. Keep it up, [Carl].
Lubs and Dubs that aren’t for dubstep
The folks at Toymaker Television posted a neat demo of heart rhythms emulated with a microprocessor. It cycles through normal sinus rhythm, atrial fibrillation, atrial flutter, and everything else that can go wrong with your heart. We know some nurses that would have loved this in school.
Back with another interesting vidoe, [Jeri Ellsworth] once again brings us an amusing and educational hack. This time she’s made a “shooting gallery” in the style of the old arcade games that actually used projectiles. In her version however, she’s using LEDs in the targets which are detected by the gun. In an effort to keep the feel the same, she rigged up a pinball bell to ding at the appropriate times and it is quite effective.
As usual, she does a great job of breaking everything down and explaining how it all works. She shows us around her prototype so you can see how it is constructed, if you can make it through the solder gun shootout in the beginning. If she were to continue with this project beyond the functional prototype stage, we’d love to see small video clips being displayed for the targets pepper’s ghost style. Maybe we’re just having fond memories of Time Traveler.
Pinball machines, while likely considered pretty retro technology by most, are still a fun and engaging way to waste a little time. The problem with pinball machines is that they take up a lot of space, making the hobby of collecting them pretty prohibitive unless you have tons of spare room in your house.
[tbarklay] loves pinball machines but doesn’t have to room for an elaborate collection. Rather than purchase one machine, he opted to build his own pinball table that can be used to play any number of games. He repurposed an old PC to power his table, connecting it to a 24″ LCD panel for the main display board. A custom cabinet was built to contain the large LCD panel as well as the computer. A 19″ LCD screen was mounted on top of the cabinet to serve as the backglass display. A set of arcade buttons were also added to the console to provide realistic paddle control.
While we don’t have a video of his particular table in action, check out this video we found of a pinball machine that uses the same setup.

[Ed Zarick] continues work on his NBA Hangtime pinball machine with the completion of the scoreboard and backglass. You should remember this project as we already covered the layer audio he developed for the system. Now he’s proving to be a protoboard master, using point-to-point techniques to build a pair of two and a half digit LED displays for team scores, as well as a shot clock timer and other status indicators.
The lighting board that controls it all is commanded via the i2c protocol, just like the three audio modules. It uses shift registers along with MOSFETs and [Ed] has taken the time to add pin headers and sockets for board interconnects. As is true with the audio system, one Arduino Mega acts as the master on the i2c bus and you’ll notice in the video after the break that the display works in perfect harmony with the sound effects.
We can’t wait to see what he comes up with for the play field!

[Ed Zarick] is preparing his pinball project and wants to have authentic sound to go with the game play. The game is modeled after NBA Hangtime and in addition to music he also needs a wide range of sound effects to beef up the experience. To make this all happen at once he developed a set of Arduino WAV shields controlled by an Arduino Mega.
As you can see above, there are three ATmega328 chips which run the Arduino boot loader and each interface with one of the three green WAV shields. That set of chips listens for commands over and i2c protocol, and once they receive instructions they play can play the chosen file without affecting the other shields.
But to have the authentic sounds you first need to acquire the audio samples. [Ed] grabbed a ROM of the original video game and dumped all of the audio samples. From there it was a chore to listen to and catalog the sounds for SD card playback with the pinball version of the game. But it’s well worth the effort as the sound will end up tying the whole experience together.

[Mark Gibson] sent us a load of details on his build, a WWVB atomic clock using a pinball machine marquee (PDF). This is the upright portion of an old machine that used electromechanical displays instead of digital electronics. It’s big, noisy, and seeing it running might make you a bit giddy. Luckily he included video that shows it working on both the outside and the inside.
It took a bit of probing to discover the connections for relays that control the display. From there he used optoisolation to drive them with an Arduino. With this hurdle behind him, [Mark] set out to add atomic clock accuracy. He picked up a WWVB module and added it to the mix.
Check out his build log in PDF form linked above. He went out of his way to explain how the original parts work, and the processes he used during prototyping. For more of those juicy details we’ve added a photo gallery and his video after the break.
Didn’t get enough pinball goodness from this project? Check out the this digital gas plasma display pulled and reused from a much more modern pinball machine. Oh, and there’s always Bill Paxton Pinball.

You won’t find those familiar steel balls inside this mini-pinball cabinet. That’s because [Luis’] latest creation is a fun way to play virtual pinball. The playing field is a 10″ LCD screen with an accompanying 8″ screen in the marquee. Inside the well-crafted case you’ll find a mini-ITX motherboard running HyperPin, a frontend software suite for LCD-based virtual pinball. He’s also using PinMame for the score board that was often provided by a gas plasma display on newer mechanical machines. There’s video after the break, and take a moment to check out [Luis’] other mini-cabinet builds.
What’s that you say? No substitute for the real thing? That’s exactly what [Ben Heck] thinks too.
